SPRING ASSEMBLY.

Application filed September To all whom t may colli/cern.'

Be it known that l, Mrs. ELIZABETH M. Fermin-VND, a citizen of theUnited States, residing` at Kokomo, .in the county et Howard and Stateoit Indiana, have invented a nenv and useful Spring Assembly, ot whichthe following is a specification.

This invention relates to spring` assemblies tor beds.I seats and allarticles Where spring seats or backs are used.

VYlhe object of' the invention is to provide a spring assembly in whichthe springs are independent one of the other being fastened only at thesmall ends leaving each tree trom interterencc with other springs ot theassembly roducingl a very flexible as Well as durable assembly. c

`itinother object is to provide an assembly ot this character in whichrepairs and replacements may be made instantly by removing the detectiveunit only and which is. so constructed that the springs can be removedand packed in small space and reassembled with little time and ettort.

Another object is to so construct and mount the springs that a largeflat supportingsurface is provided on which the, mattress may restdirect Without anyT intervenine elements.

lilith the foregoing and other objects in vieiv which will appear as thedescription proceeds, the invention resides in the combi nation andarrangement of parts and in the details ot construction hereinafterdescribed and claimed. it being understood that cl'ianges in the preciseembodiment of the invention` herein disclosed, may be made vithin thescope ot what is claimed Without departing from the spirit ot theinvention.

ln the accompanying drauf'ings :t

to 4, a spring assembly constructed in accoi-dance with this inventionfor use in connection with metal slats is shown; A plurality ot metalslats 1 are designed to be mounted on the side rails 7 ot a bed, saidrails having' laterally extending flanges (3 shown for supporting slats.These slats 1 each have right angularly extending flanges 2 along` theirside edges' and are bolted at their ends to slat spacers shown in thetorni otl metal bars or straps 3 which are of anv desired lengthaccording to the distance it is desired to space the slats. These strapsS are provided at their ends with dependingl flanges #t which aredesigned to abut when in operative position as' shown in Figs. i and 2.

Mounted to slide longitudinally on the slats 1 are spring spacers 5 hereshown in the torni ot plates having their side edges flanged as shown at8 and provided with in turned hooks or lips 9 along their lower edgestor engaging the tianges 2 of the slats as is shown clearly in Figs. 2and 3.

These platesl 5 are ot any suitable length according to the distance itis desired to space the springs to be carried thereby. These plates 5are provided With upstanding` collars shown at 10 in Fie'. land 10CL inFig. 3. said collars being alike except that in Fig. 3 they are tlaredWhile in Fig. i the Walls are straight.` These collars' havinginternalthreads 11 to torm sockets to receive one end ot the spiral springs 12constituting` a part of the assembly. The smaller ends ot these springs12 are closely coiled as shown at 13 in Figs. 1 and 3 and are designedto tit and be threaded into the sockets formed bv the collars on'theplates 5 so that the springs will be securely connected againstaccidental disengagement from said plates.

The upper Wider ends of the springs have their .tinal coils 14 arrangedin horizontal alinement With each other to form a Wide flat supportingsurface the termina-ls 15 ot said coils being hooked-shaped and bentaround the adjacent coils to hold them iu this position.

In the use of this device the springholding plates 5 are slippedlongitudinally on the slats 1 and arranged With their adjacent endsabutting as shown in Fig. 1. The sla-ts after the plates 5 are mountedthereon are then bolted to the spacing straps 3, the straps carried bythe respective slats abutting at their ends as shown in Figs. 1 and 2.The

springs 12 may be applied to the plates 5 either before or after saidplates are mounted on the slats. These springs may be quickly screwedinto the sockets 10 or 10a and when so applied form individual resilientsupports for a mattress or other, articles to be mounted thereon. Shouldone of these springs be broken or bent to suchan extent as to render ituseless it may be quickly re moved and another substituted Without inany Way interfering with the others.

ln the form shown in Figs. and 6 the plates 5 are exactly like plates 5except that they have no flanges and are designed for use in connectionWith Wooden slats on the upper faces of Which they rest and are securedby screws passing through openings 16 in the ends of the plates. Thecollar 10b isexactly like collar shown in Fig. l and supports a spring12 in the same manner as do the other holders.

ltvvill be obvious that While this spring assembly is primarilydesignedfor use in connection with beds, car seats andthe Alike it maybe used Wherever a yieldable cushion of this character is desired.

It is of eourseunderstood that the Wooden i slats in connection withwhich the holders 5 areeinployed may beequipped with the spacers `3inthe saine manner as are slats 1 except that. screws are preferablyused instead of bolts for connecting the slats with the spacers. l

Various changes in theform, shape,.pro portion and other minor detailsof construction may be made Without departing from` the principle v`orsacrificing. any of the advantagesof the claimed invention.

l .claim i 1. A springA assembly of the class de scribed comprisingcombined spring holders and spacers, each in the form of a plate havinga collar rising therefrom and threaded to receive a spring, slats onwhich said plates are designed to be slidably mounted, said slats andplates having inter-engaging means to hold them connected, and permitthem to move longitudinally relatively to each other, and spiral springshaving one end closely coiled to lit the threads of said collar.

2. A spring assembly ofthe class described comprising combined springholders, and spacers each in the form of a plate having a collar risingtherefrom and internally threaded to form a socket, slats on which saidplates are designed to be mounted, spiral springs having one end closelycoiled to fit and screw into said sockets, and slat spacers secured tothe ends of the slats and extending transversely thereof and projectingl on opposite sides of the slats, said spacers being designed to abutto hold the lslats; desired distances apart.

Il. The combination with metal slats having side flanges; of plateshaving guides along` their side edges to engage the flanges of saidslats, coiled springs detachably mounted on said plates and slat spacingstraps seein-cd intermediate their ends to said slats and projectingbeyond opposite sides thereof, sai-d straps having their ends flanged toform abutments.`

ln testimony that l claim the foregoing as my own, l hare heretoa'liixed my signature Yin the presence of .two Witnesses.
